Abstract

Išradimas priklauso chemijos sričiai ir gali būti naudojamas katijoniniams flokuliantams iš krakmolo, tinkamiems naudoti pramoninių ir komunalinių nuotekų bei nuotekų dumblo perdirbimo procesuose, gaminti. Katijoninis krakmolo flokuliantas su prieinamomis polianijonams N-(2-hidroksi)propil-3-trimetilamonio grupėmis gaunamas eterinant krakmolo mikroganules glicidiltrimetilamonio chloridu, po to disperguojant mišinį sudarytą iš eterinimo reakcijos mišinio ir vandenilio peroksido tirpalo kambario temperatūroje šlyties jėgomis.
